Area Forecast Discussion
National Weather Service Houston/Galveston TX
1002 AM CDT Tue Sep 26 2017
.DISCUSSION...
Radar is looking rather quiet this morning but daytime heating
will once again spur development later this afternoon. Satellite
derive PW fields show deeper moisture over the SW zones with
drier air to the NE. Previous forecast tapered PoPs higher to the
SW and lower NE and this appears to be on track. 12z soundings
support high temperatures between 88 and 92 degrees and Max T
grids support this range, leaning toward the warmer side. Made
some minor tweaks but otherwise the previous forecast looks on
track. 43

.PREV DISCUSSION... /ISSUED 634 AM CDT Tue Sep 26 2017/
AVIATION...
TAF sites are VFR early this morning with some high clouds streaming
across the area from the west. Could see a little bit of fog development
in the next hour or two. If high clouds don`t interfere, some SHRA
development will be possible with daytime heating with the greatest
coverage this morning expected mainly out west and this afternoon along
any sea breeze boundary that moves inland. Quiet tonight with patchy
fog possible again inland areas. 42
PREV DISCUSSION... /ISSUED 340 AM CDT Tue Sep 26 2017/
DISCUSSION...
Largely seasonable weather for much of the week is expected, though
some indirect impacts to our area may be seen thanks to a
potentially prolonged precipitation event far to our west over
portions of South Texas and northern Mexico. More significant change
looks to come at the end of the week as a front backdoors through
the area, followed by an influx of drier and slightly cooler air.
However, fans of fall weather shouldn`t get too excited, as the
impact of high temperatures will be pretty modest, and more summer-
like conditions look to return early next week.
MARINE...
Light to moderate east to southeast winds along with seas in a 1 to
3 foot range will continue through Wednesday night. Winds will
become more northeasterly beginning on Thursday with the approach
and eventual passage of a cold front. This moderate northeast flow
(some caution flags might be needed) along with building seas can be
expected at the end of the week and on into the upcoming weekend.
With an anticipated prolonged northeasterly fetch on already
slightly above normal tides, some minor coastal run up issues might
develop as early as the end of the week and possibly extending into
the start of next week. 42
